Well guys the disc I have is a single disc with a mounting bracket of sorts on top. the plow I have is an A-19 I think? I plowed yesterday and it went great! I kept the rpm's down and let the governor regulate my speed. It made me feel good seeing the full length rows laying over as I made each pass. After plowing I put on this rake I have that has curved tines, 4 on back, 3 middle and 2 in front (I think) and raked up the bigger grass clumps and blackberry roots. Oh, and as I've read on one of these boards, I added 1 cup of diesel to my fuel for extra top end lube.
